Subject[PATCH] leds: netxbig: remove legacy board-file support
Date
Since commit ebc278f15759 ("ARM: mvebu: remove static LED setup for
netxbig boards"), no one in upstream passes in the platform data to
this driver.

Squash leds-kirkwood-netxbig.h into the driver, and remove the legacy
board-file support.
